Question 326525
{{{((d/a^2))/((d^2/a^3))}}}
<pre><b>
The two denominators {{{a^2}}} and {{{a^3}}} have an LCD of {{{red(a^3)}}}.
Put that over 1, {{{red((a^3/1))}}}. Now multiply top and bottom by that

{{{((d/a^2)red((a^3/1)))/((d^2/a^3)red((a^3/1)))}}}

Now cancel:

{{{((d/cross(a^2))red((a^cross(3)/1)))/((d^2/cross(a^3))red((cross(a^3)/1)))}}}


{{{d*red(a)/d^2}}}

Cancel:

{{{cross(d)red(a)/d^cross(2)}}}

{{{red(a)/d}}}
